HEEL-LIFT ALINING, PRESSING, AND NAILING MACHINE.

Original application filed March 20, 1918, Serial No. 283,693. Divided and this application filed September 15, 1920. Serial No. 410,444.

To all whom it may concem:

Be it known that I, ERASTUS E. WINK- LEY, a citizen of the United States, residing at Lynn, in the county of Essex and State 5 of Massachusetts, have invented certain new and useful Improvements in Heel-Lift Alining, Pressing, and Nailing Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. 7

This invention relates to machines for use in the manufacture of shoe heels and more particularly to a machine for alining, pressing, and nailing the component lifts of loosely assembled heels.

One of the general objects of the invention is to provide a machine of the above named character which shall be of rela-.

tively compact, durable and inexpensive construction, and which shall uniformly perform its several functions in a rapid, effective and reliable manner.

Another object of the invention is to provide a machine of the character above indicated embodying an improved form for alining and pressing a loosely assembled heel before it is permanently secured together, and which shall function in such manner as to produce tapered heel blanks of substantially regular and perfectly alined lifts, thus insuring a uniformly consolidated and dense heel, free from irregularities and opener checked joints after being subjected to heavy pressure in a heelco1npressor. By thus producing substzimtially perfectly alined heel-piles, it becomes feasible to reduce the size of the component lifts, since the usual liberal allowances for subsequent illllllllllflg' operations may be materially lessened.

This result is secured through the agency of a feature which comprises an aliuing and clamping form for tapered heels that is i operated in two distinct stages; the first,

to close in upon the loosely assembled lifts and ahne them while in loose order, in which condition the freshly pasted lifts may be laterally shifted and perfectly alined with facility, and then to angula-rly open up slightly. to final rigid clamping position to conform to the'shape of the heel when the lifts are pressed into intimate engagement in close order, after which the loosely assembled and alined lifts are forced into the form in its final clamping position and subjected to pressure preparatory to being permanently secured together. In preliminarily alining the lifts, the cooperating alining members of the form are brought into predetermined angular positions which correspond to the previously determined angularities or slopes of the heel while its lifts are in loose order. In the open final clamping position, however, the angularities of the members are somewhat greater and are determined in advance to correspond to the slopes of the heel when it shall have been pressed into its final close order formation. Thus, when the loosely alined lifts are pressed into the form in its final clamping position, it is impossible for any of the lifts, and particularly the wedge lifts, to shift laterally or squeeze out of alinement, as is likely to occur in prior art machines of this type which have no provisions for changing the angularity of the form when the heels are subjected to final pressure.

Another object of the invention is to vide, in a heel lift alining, pressing nailing machine, a form for alining and pressing loosely assembled and freshly pasted heels and clamping them firmly in position while the component lifts are nailed together by an autormitically supplied nail ing device which is so mined as to be en tirely free of excess paste that may accumulate in the form during the operation of the -machine.

To this end, a feature of the invention resides in the provision of an alining and pressing form comprising a horizontally disposed breast support upon which the loosely assembled heel rests upon its breast and an automatically supplied nailing device disposed laterally of the form, in a proand

position free of paste and operatingin a horizontal plane to drive a nail through the component lifts. Moreover, the horizontal disposition of the nailing device contributes towards accuracy and uniformity in driving the nails in definite positions with respect to the breasts of the heels, inasmuch as the nails that are automatically supplied to the nailing device always gravitate to a fixed position and, therefore, are driven into the heels in predetermined similar positions, thereby permitting the operator to adjust the angularity of the breast support so as to insure that the nail is located free of that portion of the heel that will later be trimmed off or undercut, as is the caseparticularly iii-high womens heels. i v

A still further object of the invention is to provide in amachine of the above indicated classa semi-automatic power operated alining and pressing form, the initialoperation of which is effected manually in such manner as to protect the operators fingers from injury when the power is applied.

Accordingly, another feature of the invention contemplates the provision of a manually operable controlling handle which actuates theform to partially aline'the lifts and which is brought forward by the operator to a position inwhich it is impossible for the fingers to be indanger beforeit au tomatically throws in the clutch to connect the machine to the source of power:

These and other objects of the'inv'ent-ion.

and the features of construction by meansof which they are'attained, will become ap parent from' the following description of;

In the drawings the invention is illustrated as embodied in a heel lift alining, pressing and nailing mechanism having the same construction as corresponding mechanism shown and described in epplicants pending application for heel building machines, Serial No. 283,693, filed March 20, 1919, of which the present application is a division; V

The illustrative machine comprises, in general, a supporting frame upon which the variousparts of the machine are mounted;

a heel receiving and holding device, coinprising a breast plate 20 and a plurality of relatively movable pressure members and 2i, in which loosely assembled heels or heelpilcs are placed by the operator; a lift alining form comprising a plurality of alining jaws 26, 28, ll), 32' and 3-1:. for cooperating with the component hits of the heel to effect their alinemcnt; a pressure applying" device including the pressure members 22 and 2'3. which also constitute parts of the heel receiving and holding device hereinhefore 170-" ferred to, and which serve to force the pro liminarily alined lifts into the alining form and subject them to pressure; a nailing device including a nail driving pin 36 for nail.- ing together the alined and pressed lifts of the heel; and an automatic nail supplying mechanism including a nail holder 38 and a feed tube for supplying nails to the nailing device.

The mechanism of the present machine is semi-automatic in operation, being under the direct control of the operator, and is adapted to aline the loosely assembled lifts of the heel, to subicct the heel to pressure and to clamp it firmly in its final form while its component lifts are being permanently nailed together. The mezhanism is of the single cycle type in which the operation is automatically arrested after the completion of each full cycle of operations upon a. heel. The mechanism may be adjusted to operate upon heels of various types, but it is particularly adapted to operate upon tapered heels.

The supporting frame of the machine comprises lower side frames 42 and f4 (Fig. l) and upper frame members 46 and 48 (see also Fig. which are disposed above the side frames 42 and 4A: and are secured thereto. The upper side frames -16 and .1-8 are connected at their forward endsby a front plate 50 and carry upon them a cap plate 52 which constitutes the table of the machine. The cap plate 52 is bolted to the upper frame members 46 and to the front plate 50 and its forward portion 54 (Fig. 7) is relatively narrow and supports the breast plate 20.

The mechanism may be driven from any suitable source of power. As shown in Fig. 1, power is supplied to the mechanism from a sprocket 54: that is mounted upon a power shaft 56 which has a bearing in the lower side frame 44. A chain 58 connects the sprocket 54 with a sprocket 60 that is keyed to a cam shaft 62 which is journaled in the upper frame members 46 and 4:8 and is continuously driven.

The operation of the machine is controlled through the agency of a clutch which coniprises clutch, disk 64 (Figs. 3 and 9) fixed to the cam shaft 62 and having lateral projections or teeth 66. A clutch lever 68 (Figs. 3 and 7) cooperates with the rotating; clutch disk 64 and is in the form of a yoke. which is pivotally mounted upon a pin 70, lhat extends through the hub portion of a rain 7 keyed to a loosely mounted sleeve 74 7 and 9) that extends to the left the entire width of the machinmand which car 1' a plnralita of cams T6. 78 and 8t) lhnt are also keyed diereto.

'lhe clutch lever (38 is normally urged into operative position in engagement with one of the clutch dish nnjections 56 by means of a spring; and its disconnection therc from is effected after each complete revolution thereof. by means of a wedge cam Sa which forms a part of a control. arm 86 that is pivotally mounted upon a rod 88 extending between the upper side frames. The operation of the control arm. is governed in a manner to be hereinafter described, and

when said control arm is moved into its released position, as shown in Fig. 7, the clutch is thrown into action to connect the normallyloose sleeve 74, carrying the several operating cams, to the continuously driven cam shaft 62 whereby the cycle of operation of the mechanism is initiated. ."tfter the cycle of o )eration has been completed. the control arm 86 moved into its stop position, as

shown in F 9, in which the rotating clutch disconnected and the several operating cams are brought to rest. In order to overcome the inertia of the rotating clutch cam 68 when it is thus disengaged a spring-presscd pin 90 is provided upon the control arm 86 against which the outer end of the clutch lever 68 is brought to rest.

Having described the supporting frame of the machine and the manner of operating; the clutch by means of which power is connected to and disconnected from the several cams 72, 76, 78 and 80, the construction and operation of those parts which are controlled and actuated by said cams will now be set forth.

When a loosely assembled heel-pile is placed by the operator in the heel receiving and holding device of the machine it is positioned with its breast resting upon the horizontally disposed breastplate 20. as shown in Fig". 10. plate 20 are the pressure members 22 and 24; between which the component lifts of the heelcare disposed and loosely supported in position. The pressure member 2-1 is stationarily and removably fixed'to a boss 92 Cooperating with. the breast Ti -O (Fig. 7) on the cap plate 52 and projects forwardly to permit its rounded forward end to engage the tread faced end of the heel. The relatively movable pressure member 22 is adjust-ably mounted by a. pivot upon one end of a supporting' rod 96 so that it may accommodate itself to the angularity or inclination of the base-left of the heel. The breast plate 20 is removably secured in position so that it may be replaced by other similar liireast plates of different thicknesses and inclinations or tapers to properly PUf-dtion heels of varying shapes and forms for the nailiuo' operation. The relatively nar row forward end 54- of the cap plate 52 provided with a trough 98 which surrounds the-breast plate 24) and intended to collect any excess of paste that may drip, or may be squeezed out from between the component lifts of the heel.

After p acing a loosely assembled and freshly pasted heel into the receiving and holding device where it rests upon its breast with its component lifts loosely assembled, or in loose order, as shown in Fig. 10, it is necessary to laterally shift the lifts while thus loosely arranged to effect their aline ment.

This accomplished by means of'the alin' ing form comprising the pivotally mounted alining jaws 26, 28,- 30, 32 and 3st. Normally the alining aws of the formoccup'y'their open positions, as illustrated in Figs. 3 and- 13, the upper jaw 26. being adapted to be" brought mto engagement with the upper or rear edges of the lifts, the jaws 28 and 32 being disposed on the left hand side of the heel and adapted to be brought into alining engagement with one side of the component lifts, and the jaws 30 and being disposed on the opposite side of theheel to perform similar functions.

The upper jaw 26 is pivoted upon a pin (Fig.7) to swing in a vertical plane and said pin is carried at the forward end of a bifurcated arm 102, the rear end. of which is pivotally associated with a lug 104: that projects upwardly from the cap plate 52. The bifurcated arm 102 is provided with an upward projection 106 between which and the rear end of the cap plate, a spring 108 is connected, for the purpose of maintaining a roll 110 (Fig. 10), carried on the extended pin 100, in operative position.

The several pairs of. side alining jaws 28 and 32, and 30 and 34L are mounted to swing in horizontal planes, each pair of jaws being pivotally mounted upon a vertical pin 112 (Figs. 3 and 13) at the end of a horizontally disposed swinging supporting arm 11%, said supporting arm.be ing pivoted upon a stud 116 and being biased to its outermost position by means of a spring 118 that is attached between it and a point onthe cap plate 52. The lower jaws 28 and 30 are also provided with outwardly extending arms 120 to the ends of which are attached springs 122 which serve to yieldin'gly urge them into their inward aliiring positions. The upper alining jaws 32 and 31, however, are merely pivoted upon the pins 112 and are free to occupy any position they may assume.

The several jaws 26 to 3 1, inclusive, of the aliuing form are adapted to' be actuated through the agency of a manually op crable actuating lever 121 which assumes the position illustrated in Figs. 3 and13' when the alining jaws are open. The actuating lever 121 (Figs. 3, 4, 5 and 7) isyoke shaped in form, having a plurality of arms 126, the lower ends of which are pivotally mounted upon a shaft 128' extending between the respective upper side frames, and the upper end of the lever is provided with a handle 130 by means of which it may be actuated. Between the relatively adjacent upper portions of the side arms 126 of the actuating; lever 124,- a member 1352 (Figs.

The function of this roll is to engage a cam surface (Fig. 7) provided upon the upper alini ng jaw 26, and in conjunction with the engagement of a tail-piece 1&2 of the mem her 132 with the roll 110 carried upon the pin 100, to actuate the upper alining jaw 26 into its preliminary alining and subsequent final clamping positions when the actuating lever 124 is manually brought for ward by the operator. A spring 1 14 interposed betweenthe free end of the alining-jaw 26 and the lever 124 serves to bias said jaw to its open position.

The several pairs of side alining jaws 28 and 32, and 30 and 3d are also actuated by the forward movement of the actuating lever 124;. For this purpose, each arm 126 of the actuating lever 124 is provided with an ad'justably positioned member 146 (Figs. 2, 1 and 13) which carries a roll 1 18 upon a pin 150 that extends down wardly from said member a material distance. Each of the roll carrying members 146 is provided with a laterally extending arm 152 having an angular-1y disposed slot ted end 154., the arm 152 being also provided with a slot156 (Fig. 2). The arm 152 is seated in a notch 158 in the side arm 126- of the actuating lever and is secured thereto by means of a bolt 160 (Fig. 13) which projects through the slot 156 and intothe rear edge of the side arm 126. For purposes of lateral adjustment of the roll 148 and the pin 150, an adjusting bolt 162 is provided. which projects through the slotted end154: of the arm 152 and is threaded into a boss 16% that projects laterally from the side arm 126.

hen the manually operable actuating lever 124 occupies its released position, as shown in Figs. 1, 3 and 13, the dmvnwardly extending ends of the pins 150 engage the arms 120 of the lower alining jaws 28 and 30- and hold said jaws in their open positions against the action of the springs 122.

Asthe actuating lever 12 i: is brought forward by the operator, the advance movement of the pins 150 permits the springs 122 to progressively swing the lower a lining jaws 28 and 30 into engagement with the lateral edges of the component lifts of the loosely assembled heel that rests in the receiving and holding device. The lower j a ws, therefore, tend to yieldingly aline the ifts.

engagement with the lateral edges of the loosely assembled lifts to effect their alinement.

Concurrently with this alining operation of the side alining jaws, the forward moveinent ofthe actuating lever 12a also actuates the upper alining jaw 26 into alining position by reason of the engagement of the roll 13 i with the cam surface 140 of said jaw in conjunction with the cooperation of the tail-piece 142 with the roll 110. The upper alining jaw 26, therefore, is forced downwardly into engagen'ient with the upper or rear ends of the loosely assembled lifts to force their breast edges firmly against the breast plate 20.

An important feature of the invention resides in the peculiar operation of the alining jaws constituting the alining form, which are actuated in two stages or steps, in the first of which the upper jaw 26 and two upper side jaws 32 and Si are brought into predetermined alining positions, the angularity or inclination of which corresponds substantially to the slope or inclination of the engaged portions of the heel'while the component lifts thereof are loosely assembled, or in loose order." The desired angular positions of the jaws in their preliminary alining positions is secured by the use of jaws having properly designed cam surfaces and by adjustment in the positions of the operating rolls 134; and 1 18, the jaws being replaced by other suitable ones to secure the requisite angularity, and the positions of the rolls being suit-ably adjusted to accommodate heels of different sizes but of similar slopes or tapers.

n the second stage} of operation of the alining form, the several jaws thereof are permitted to be opened up slightly to a predetermined greater inclination or angularity which conforms to the slope or inclination of the heel after the lifts have been forced into the form and subjected to pressure to 'bring, them into intimate contact, or into close order, it being evident that the slope of a heel of closely assembled lifts is greater in angularity than that of the same heel while the lifts are loosely assembled. This change in the positions ofthe alining jaws, how .ver, is not effected until the heel is subjected to pressure, which is effected in the following manner.

' Assuming the lifts to be preliminarily alined in their loose order, as indicated in Fig. 10, the pressure member 22 is actuated to apply pressure thereto and clamp the lifts against the stationary pressure member 24. As already stated, the pressure member 22 is pivotally mounted upon the rod 96 so that it may accommodate itself to any pitch of heel. This rod 96 projects through an up wardly ext-ending portion 168 (Fig. 7) of a plunger 170, and is secured thereto by suitable nuts 172. The plunger 170 is slidably mounted for back and forth motion in an opening provided in an enlarged portion 174: (Fig. 9) of the cap plate 52, and said plunger projects to the rear beyond said enlarged portion and carries a plurality of rolls 176 and 178 (Fig. 7). The forward end of the plunger 170 is provided with a recess to receive a coiled spring 180 which is seated against the bottom of the recess and against an upwardly projecting arm 182 that forms a part of the front plate 50. The

spring 180 is relatively strong and normally urges the plunger 1T0, together with the movable pressure member 22, rearwardly to cause said pressure member to force the preliminarily alined lifts into the form composed of the several alining aws and to subject the heel to a predetermined yielding pressure,irrespective of its height.

Prior to the application of pressure to the heel, the pressure member 22 is maintained in its open and inoperative position against the action of the spring 180 by means of a bell crank 18% that is pivotally mounted upon a stud 186 carried by the side frames 4L6 and 4-8 and which acts upon the rear end of the plunger 170. The other arm of said bell crank carries a roll 188 that is adapted to cooperatively engage the cam 76. This cam is designed to permit the pressure applying spring 180 to actuate the pressure member 22 at the proper time, and to subsequently release. said pressure member by causing the bell crank 184; to act upon the end ofthe plunger 170.

As the preliminarily alined heel is yieldingly forced into the form in the manner just described, the operating rolls 13% and 1&8 that cooperate with the respective cam surfaces 1-i0 and 16% of the alining jaws 26, and 3st, pass over the points 190 and 192 of the respective cam surfaces, thereby permitting said jaws to open up to predetermined increased angularities or inclinations which as hereinbefore stated, correspond to the exact pitch of the heel after it has been subjected to pressure. The alining jaws 26, 32 and 3a are thus firmly held in their final alining and clamping positions, as shown in Figs. 4- and '4', to constitute a rigid form into which the V preliminary alined lifts are forced and subjected to pressure.

Although the lower alining jaws 28 and 30 are at first yieldingly actuated into their preliminarily alining positions by the springs 122, the forward movement of the manually operable actuating lever 12st brings the extended lower ends of the pins 150 into positions spaced slightly behind said jaws. Saidpins-therefore serve as rigid restraints or stops tor-the jaws when the jaws are spread outwardly "as the loosely assembled and preliminarily alined lilt-s are subjected to pressure. Thus, all of the alining jaws of the form are rigidly held in their final alining and clamping positions which are determined in advance to be such as to exactl v contorin to the heel-after it h-asbeen subjected to pressure. It isclear, therefore, that by reason of the two stage alining op eration no disarrangements ol' the component hits of the heel are possible and that a substantially perfectly alined heel is insured. 7

Although the initial for vard movement of the actuating lever 121- is ell'ected manually the latter part of the operation is produced by the application of power. hiioreoven-this application of power to the actuating lever is not permitted until the several jaws of the alining t'orm havebeen manually moved into substantially their preliminary alining positions, after which it is impossible for the operatorslingers to remain in the ma chinc wherethey may be injured. Furthermore having once brought the actuating lever 12litorward to a position in which power is applied thereto,ineans'is provided tor preventing the manual retraction thereof by the operator. v

To etlectthese results, the actuating lever connected to the upper end of the clutch control arm 86 by means or" a link 1% igs. 1 and 7). VV-hen the actuating lever occupies :its inoperative posit-ion, as shown in Figs. 1 and 9, the control arm '86 is maintained in such position as to prevent he clutch lever 68 from being thrown into engagement with the clutch disk 64, whereby the application of power is prevented.-

ll heu. .iowever, the actuating lever has been manually brought forward to an extent sulficient to place the jaws of the alining "form in substantially their preliminary a'lining positions. the control arm 86 withdrawn and thecl itch lever 68 released and permitted to effect an operative driving engagement with the continuously opera-ting clutch disk 6i whereby all of the cams 72, 76 78 and 80 are conne ted to the source ot'power.

.eci the power operation of the machine,

rol' 196 (Figs. land 12) that is carried t th-- 'ondol a lever 198 is dropped in a cam path 200 in the cam 80, as indicated in dot and dash lines in Fig. 12. The lever 1.578 -ally mounted upon a stud 202 oroj "=2 inwar y from the left hand side ot' the cap plate 02, and its other-end is connected by means of a link l, ha'v1ng bifurcated ends. with an arm 206 forming an integral part or the manually operable acalter the cam operates upon the roll196 to force the actuating lever 124- to its torcniost positionrand to release the several alining aws from their preliminaryalining po sitio-ns. Subsequentlythe cam T6 (Fig. 7)

releases the pressure applying spring 180 H.

and the. pressure member 22isactuated to torce-theheel into thealining jaws in their final alining and clamping positions and to subject the heel to a predetermined yielding pressure.

An additional and positive pressure is then applied to the heel in the tornnatter which the pressure member 22 is positively restrained to provide a rigid and firm backing against which the nailing mechanism may operate. To this end, an eccentric wedge cam-212 (Fig. '7) is rotatably mounted upon a. stud 214 and is actetlupon by a spring 216 that is attached through an adjustable tension device 218 to the upper end of a supporting anm 220 which projects upwardly from the cap plate An arm 222 forms a partot a bell crank with the wedge cam 25.2, and carries at its end a roll 224 thatis adapted to cooperate with the cam 7 2 on the cam shaft 62. The Wedge 0am 212 inits operative position, as shown in l 'ig. 7. co-

operatively engages the roll 176 that lined to the side of the plunger 170 to which the pressure member 22 is attached. The spring 216 is preferably heavy relative to the 'ires surc-applying spring 180, and the tension thereof is adjustable by means oi the tensioning device 218.

The cam 72 is designed and angularly positioned upon the cam shaft so that after a predetermined yielding pressure has been exerted upon thelheel through the spring 180, the roll: 22 1 on the wedge cam bell crank is disengaged from the cam 72, thereby permitting the relatively heavy spring 216 to pull the wedge'cam 212 upwardly against the roll 176. By reason of the strength of the spring and the eccentric form of the wedge cam, said cam is caused to force the plunger 170, together with the pressure member 22, toward the right to exert an additional and positive pressure upon the heel. The amount of positive pressure to which the heel 1s thus subject-ed depends entirely upon the strength of the spring 216 and, therefore, any degree of pressure may be obtained in accordance with the adjustments of the spring tensioning device 218.

With this construction it is clear that the heel, regardless of its height, is first subjected to a predetermined and substantially uniform yielding pressure that is effected by the spring 180, and thereafter, the heel is subjected to an additional predetermined amount of positive pressure through the action of the wedge cam 212. The edge cam 212 serves a double function, since it also positively locks the pressure member 22 in its final pressure-applying position so that it is positively held and constitutes a rigid backing against which the nail is driven in a manner to be later described.

The next operation is to nail together the alined and pressed heel, and this is accomplished by the nailing device comprising the nail driver 36 (Figs. 6 and 7). The nail driver 36 is horizontally disposed and projects slidably through an opening in the rear pressure member 24 which is provided with a V shaped groove 226, to which the nails" are automatically supplied by the feed tube 40 and in which the nails lie in substantially horizontal position.

The nail driver 36 is held by a' suitable chuck 228 that is mounted upon the end of a plunger 230 that is adapted to reciprocate inan opening in a longitudinal boss 232 that forms an integral part of the cap plate 52. The rear-end of the plunger 230 is provided with an adjustable end member 234 (Figs. 3 and 7) having a vertically disposed channel or groove to receive an engaging member 236 that is secured at the upper end of a bell crank 238. The end member 234: is

- also provided with a socket 2&0 to receive one end of a spring 242 that is held in a recess 2&4: in the boss 232 (Figs. 7 and 9). The spring 242, therefore, serves to urge the nail driver 36 rearwardly and to maintain it in its retracted inoperative position and, at the same time, to hold a roll 246 (Fig. 7) carried at the other end of the bell crank 238 in engagement with the cam 78 on the cam shaft 62. The cam 78' controls the operation of the nail driver 36 and is designed to positively advance the nail driver 36 to drive a nail through the component lifts of the heel after the heel has been subjected to pressure and firmly clamped in position.

freshly pasted heel in position to be nailed. This arrangement is such that the freshly pasted heel isplaced on its breast upon the breast plate 20 and the nail driver is located adjacent and to the rear thereof and operates in a horizontal plane during its nailing operation. Thus, the heel receiving and holding means and the nail driving device are disposed side by side so that any excess of paste that may be carried by the freshly pasted heel or may be squeezed out from between its lifts, cannot possibly come in con tact with the nailing apparatus, which always remains clean and free from paste and operates with reliability and effectiveness. Moreover, this arrangement also permits of the use of an automatic nail supplying mechanism which it is impossible to employ, in a position in which it may be gummed by contact with paste.

Before describing the construction ant operation of the automatic nail supplying mechanism, however, another advantageous feature of this horizontal side by side arrangement should be considered. With this arrangement, the nail receiving groove 226 is horizontally disposed and, therefore, as the nails are supplied thereto prior to the nail driving operations, said nails gravitate to and always occupy similar positions resting at one end upon their heads and at the other upon their pointed ends. This position is substantially horizontal, although slightly inclined thereto by reason of the somewhat enlarged diameter of the head of the nail. Each nail, however, occupies the same position and, therefore, must be driven into the heel in substantially definite and fixed position, it being well known in the art that nails are driven along lines in the direction in which they are positioned when the driving operation takes place.

Advantage is taken of this fact, in order to insure the proper positioning of the securing nails in the heels, and particularly in relatively high heel-piles from which hi gh Louis heels are to be made. In some forms of Louis heels the breasts of which are to be greatly under cut and which slope foiwvardly at quite extreme angles, the areas of cross sections of the heels at certain points are extremely small, which makes it necessary to carefully locate the nails which secure together the component lifts so that they shall not protrude beyond the limits of the heels in their final forms.

To adapt the alining, pressing and nailing mechanism of the present invention to operate upon heels of different styles and forms and to properly position the securing nails therein in accordance with the peculiar characteristics of the heel being operated upon, the heel receiving and holding device con'iprising the breast plate 20 and the relatively movable pressure members 22 and 24 are madeadjustable. Fig. 8 illustrates said receiving and holdingdevice adjusted to properly position and hold a heel-pile from which a high Louis heel is to be produced, the final shape, of the heel being indicated in dotted lines. In this construction, the breast plate 20 is tapering and inclined in form; the adjustable pressure member is tilted upon its pivotto,accommodate the inclinationo't' the base-lift of the heel; fwhile the rounded end of the, stationary pressure member Q-l permits theheel'tobe properly positioned'with respect thereto. The taper and thickness of the breast plate 20 is suitably chosen with respect to the particular characteristics ofthcheel to be builtin order to properly positionitso that the nail, which is always driven in apredetermined direction dependent upon its definite position in the nail receiving groove 2-26. is driven through the restricted area of the heel and in such positionthat it willnot be exposed whenthe heel breast isunder out and the lateral surface trimmed to itsfinal shape.

Referring again "to Fig. 7 after the nail has been driven bythe nail driver 36., the cam 80, (Figs. 8, and 12;) operatesthrough its cam surface 2&8 to force the cam roll 196 outwardly and, through the connections already described, :to positively throw back the actuating lever 12% of-the :alining form into its normal retracted position, as shown in Figs. 1, 12 and 13-; This operation releases the several alining and clamping jaws 26 to 34;. "inclnsive as will be miderstood. At substantially the same time the cam 72- (Figs. 3 and 71) isbrought into position to engage the rollQQl whereby the wedge cam 212 is withdrawn fromits operative position to release the plunger: 170 carrying the'pressure member Subsequently the cam 76 operates uponthe roll 188 to cause the bell crank lever 18% to, forccthe plunger 170 and its pressure member 22 forwardly against the action of the spring 180 whereby the pressure is relieved from the heel-and the heel receiving and holding device is restored to its initial open position.

Immediately after the pressure member 22 has Jeen retracted to itsopen position,

the cam 78, by reason of a raised portion 250 (Fig. 7) thereof, cooperates with the roll 24:6 and bell crank 2381 to give the nail driver 36 a slight projection forwardly to loosen the heel that may possibly have adhered to the breast plate 20. The nail driver is then immediately retracted to its initial position,

at which time the alining, pressingand nailing mechanism is'brought to rest by automatically disengaging the clutch lever-68 from the continuously rotating clutch disk ns-ec oes retraction of the main-actuating lever 124, in which position .it engages and throws out the rotatingclutcharm 6'8 whenit reaches a position in which theengagement may take place, as shown a in Fig. 9.

As already'stated, the horizontal and side a by side relation of the heel receiving and holdingdeviceandthe nail driving device permits the employment of an automatic nail supplyingmechanism. This mechanism isuadapted to supply anailto the nail re i wardlyv therefrom to: receive a rotatable supporting spider 256 that is yieldingly held in position upon a portion of the bracket 252 and which is -p-rovided with a plurality ofradial, arms, 258 that are joined by means of segmental members 260. At the extremities of the arms 258', a plurality of imward- 1y projecting pins 262 are located, and these pins 2r62r-are adapted to support the nail holder-38 which comprises an annular memberQGa having, a plurality of inwardly extendingapertured lugs-266 which setrover the pins 262 and by means of which the an: nularmember 264 is renwvably supported in position. Thenails are held in both the inner "and the outer corrugations of a corrugatedstripof sheetmaterial 268 that is secured to the periphery of the annular meniberflfia anclin order to retain the nails in the outer corrugations ofsaid strip, a plurality of bands 270 are positioned around the periphery of the corrugated strip and incontact;therewith. To support the nails, a Supporting ringer plate 272 is disposed immediately beneath the annular member 5264: and isloosely supported in position by lUU Ill)

meansqoiii' washers 272% (Fig. Ill), that are held upon screws 2T6" which i are threaded m-to l nwardl-y pro ect ng lugs 278 that are formed integrally with the annular member This .structureis: such that the annular member 2641mm be; removed from the pins 262+and, througlrthe. agency of the supportiIlg Washers 27,4, carries the supporting ring 272 with iii, The supporting ring 272 is provided with an aperture 280 thatis located beneath the corrugations of the nail hol derin: such position that as the holder is advanced in steps, the nails contained therein areprogressivelybrought over the aperture280 whereby said nails are permitted to drop tlnrongh and into the flexible feed tube-l0 which is supported by the bracket ture.

252 in'a position directly beneath said aper- During the normal operation of the nail supplying mechanism, the supporting ring 272 is restrained against rotative movement by means of a fixed pin 282 (Fig. 11) that projects into an opening in said ring when it is properly positioned.

The nail holder 38 is adapted to be advanced, one step at a time, at each cycle of operation of the alinin pressing and nailing mechanism, and its feeding movement is effected by means of a spring-pressed pawl 28% that is pivotally fmounted upon a pin 286 at the upper end of an arm 288 which forms apart of a bell crank 'pivotally mounted upon the bracket 252 by means of a pin 290. The bell crank alsocomprises an arm 292 that carries at its outer end a roll 29a which cooperatively engages a cam path 296' that is provided in a cam 298. The cam 298 is fixed to a shaft 300 journaled in the bracket that carries a sprocket 302 which is connected by means of a chain see (Fig. 1) to a sprocket 306 (Fig. 9) that is fixed by means of a set screw 307 to the sleeve 74 surrounding the cam shaft 62 and upon which the several operating cams of the machine are mounted.

Inasmuch as the nail holder 38 is advanced in steps by reason of the engagement of the pawl 28d with each outercorrugation of the corrugated member 268, and inasmuch as nails are contained in both the outer as well as the inner corrugations of said member, it is necessary to make provision for advancing the nail holder, a half corrugation at each step. To effect this result, the ratio of the sprockets 302 and 306 is so chosen that for each complete cycle of the machine, the cam 298 is rotated a half revolution, which by reason of its design,

causes the pawl 284: to advance the nail holder 38 a step corresponding to one half of a corrugation. During the next succeeding cycle of operation of the alining, pressing and nailing mechanism, the cam 298 completes the other half of its revolution during which it advances the nail holder 38 another half corrugation. The pawl is then retracted. to engage the next suceeding corrugation. .In this manner, the nail holder 38 is advanced in steps, a half corrugation at a time for each cycle of operations of the alining, pressing and nailing mechanism, whereby the nails contained-in the inner and. outer corrugations of the corrugated strip 268 are progressively positioned over the aperture 280 and feed tube 40 and are supplied one at a time through the tube d0 to the nail receiving groove 226 in position to be .acted upon by the nail driver 36.

When the nail holder 38 has been emptied, the annular member 264, together with the supporting ring 272. may be removed bodily for reloading. To facilitatev the removal of the nail holder, a manually operated detent or latch 308'is provided which is pivoted upona pin 310 and may be swung into position' to engage the pawl 28 i and positively hold it in inoperative position to permit the nail holder 38 to be raised from the supporting pins 262 and removed. To prevent rela tive rotative movement between the annular member 265 and the'supporting ring 272 carried thereby upon the washers 27%, said annular member 26%- is provided with a spring-pressed pin 312 (Fig. 11) that, when the holder is removed, is adapted to be projected into the opening in the ring 2T2 that receives the fixed pin 282 when the holder is in position. This construction insures that no nails are lost through the feeding apcr ture 280 after the nail holder has been loaded.

When the nail holder 38 is again placed in operative position, upon the pins 262, the pin 282 projects into the opening in the supporting ring 272 and by reason thereof, pushes out the spring-pressed pin 312, whereby the supporting ring 272 is held stationary in position, while the annular member 26% resting upon the spider 256 is permitted to be stopped along in the manner already described to successively deliver the nails into the feed tube 40.
